What’s the Cause of Algae Growth in Aquariums?

The cause for algae growth in aquariums is either due to high nutrient levels in the water or an insufficient number of algae eaters to consume the excess nutrients.

The most common type of algae found in aquariums is the green species. Brown algae is also prevalent, followed by blue. Algae can grow on any surface of the tank including the tank glass and the lights, which are both popular targets for algae growth. Additionally, you may notice that when aquarium lights are on, they may look like they’re glowing green. This is because when light penetrates into water, it emits a greenish

Different Types of Algae & How to Get Rid of Them

Algae are very common in an aquarium. They can grow on any surface in the tank, be it rocks, stones or even the glass. Algae grows when there is too much light and oxygen in the water.

There are two types of algae that bounce back in the presence of light:

1) Green algae which is most common and can be identified by its green hue and slimy texture

2) Brown algae which has a different color and has a rougher feel to it than green algae.

Ways to Remove Algae from an Aquarium

Poor Maintenance of the aquarium

Aquariums that are not properly cleaned tend to accumulate algae over time because light can reach where there is no surface area for it grow on. The best way to remove algae from an aquarium is by using a bleach method- pouring this mixture on all surfaces of the tank and scrubbing with a clean cloth until its clear again! You can only do this when the algae is uncontrollable you need to empty the tank, clean all your equipment’s, rinse well and then keep it for drying and then reintroduce to the tank.

Please note that if the tank is not cleaned well after using bleach it might kill your fish so please beware of using this method and use it as a last resort.

Check your water for phosphates

Check your water source and use a testing kit to check if there are high level of concentration of phosphate in your tap water. The best way to avoid is using RO water for your tank. They are commercial available phosphate removers but I wouldn’t recommend it.

Excessive dosage of nutrients for plants

Always check the level of nutrients you are dosing for your planted aquarium either excess of it or less of it can lead to algae problems. Always plant densely in your aquarium as it tends to control algae and absorb excess nutrients from water.

If there is excess nutrients in your tank then you are use temporarily activated carbon in your filters and it will absorb all the nutrients from the tank. Please don’t use it long term as your plants will be devoid of any nutrients.

Use of high quality filters

Algae grows due to excess nutrients and good quality filters can always the level of nutrients in the water as the beneficial bacteria in the filter media will help to cycle the tank and take out any excess nutrients in the water column.

Please always invest on a good quality external canister filter as they tend to work better for a aquarium and it will help to keep the tank stable.

Maintain Good Water Quality

In addition to the point1, maintaining good water quality is another factor for controlling algae. You need to change 15% to 20% of water every week to keep the algae growth at bay.

Check the duration of light

If you are using a planted aquarium and if you are running your aquarium for 8 to 10 hours it can lead to algae issues. Reduce the duration of the light to 6 hours and see the progress. If you are having severe problem of algae then you can turn off the lights completely for 2-3 days and then revisit the situation after that.

Another good way is to use light controllers which can gradually increase the intensity of the LED light in your aquarium so if you are running for 8 hours, in the first hour and the last hour you can set the light to be at 25% and only for remaining hours it can be at 100%. You can play around, adjust according to your fish tank and this should help you to control the algae.

Use Algae eating fishes or invertebrate’s

There are lot of fishes and invertebrates which thrive on the algae, it is source of food for them. You can use plecos, amano shrimps, Siamese Algae Eater ,Chinese Algae Eater, Otocinclus Catfish, Nerite Snails

Using plants like Pothos & floating plants

Use of the floating plants like Salvinia, Pistia Water Lettuce etc. also helps in controlling algae as they tend to absorb excess nitrates from water. If you are using tank which doesn’t any plants also Pothos/Money plant only the root of the plant can be in the water and remaining plant will be outside the tank. They will absorb excess nutrient and grow well.

Conclusion

There is no one single solution to tackling algae issue, we need to identify and eliminate the root cause to control algae. You will never be able to remove algae 100% there will always be small amounts of algae in your tank and it is good for your fish and invertebrate’s.
